Title: Method of separating a bundle of a multiplicity of monofilaments from a rotating bobbin and apparatus therefor
IPC: B65H51/005
Filed: 1969-12-11
Abstract: 1287307 Unwinding yarns ODA GOSEN KOGYO CO Ltd 11 Dec 1969 [22 Sept 1969] 60573/69 Heading D1J [Also in Division F2] A method of separating a non-twisted bundle of a multiplicity of mono-filaments into individual or groups of filaments 2, comprises drawing said bundle 1 from a rotating bobbin 4 without causing twisting of the bundle being drawn, around said pirns 9 while maintaining the running filaments under a substantially constant tension by progressively decreasing the speed of the separated filaments 2 being wound up. Variable speed. In Fig. 1 the reduction in speed of the filaments 2 is achieved by a feed screw 51 moving a cone belt feeder 14 relatively to driving and driven cones 12, 13. Clutch control. In Fig. 1 a belt 18 interconnects the driven cone 13 with a drive 10 to the pirns 9. A tension pulley 15, acting on the belt 18, is coupled by a cable 26 to clutch control means, Figs. 3 and 4 such that when tension is exerted in the cable 26 by the clutch the belt 18 establishes a driving relationship between the cone 13 and the pinions 9, Fig. 4. The clutch comprises a male cone 24, Fig. 4, keyed to a slowly rotating shaft 22. A first handle 21 is used to manually slide the male cone 24 along the shaft 22 until the cone 24 engages in the female cone 25. The female cone 25 is coupled to the cable 26. A second handle  20 permits the female cone 25 to be manually rotated to a setting in which an initial tension is manually imposed on the cable 26 and so cause the belt 18 to drive pinion 9, there being a pawl and ratchet arrangement 32 for holding the female clutch against reversed rotation. The driven shaft 22 causes the male cone 24 to rotate the female cone 25 still further and, by so doing, gradually increases the tension in the cable 26 and hence the driving effect of the belt 18. The increasing tension in the cable 26 continues until a cam surface 30 on the female cone acts on a contact 31 on the male cone to separate the clutch cones, the ratchet 32 holding the female cone 25 at its last setting. When the tension in the cable 26 has to be released lever 34 is raised to release the pawls 33 from the ratchet.  Traverse. A lever 45, Fig. 10, rocking about a pivot 46 is coupled to a main traversing rod 65 at its lower end, and at its upper end to a shaft 49 that carries yarn guide means. The pivot 46 is carried by a mount 62 that is in threaded engagement with a screw 61 in a guide bracket 64. Gear means couple the screw 61 to the shaft 52 to cause a displacement of the pivot 46 during the winding of the pirns 9 and hence a continual reduction in the traverse of the yarns on the pirns.

Abstract: 1,262,211. Joining strip end to end; punching. SECOR AB. 12 Dec., 1969, No. 60792/69. Headings B3A, B3J and B3W. In a machine for joining the ends of two metal strips 1 and 2, punches 27 and dies 26 act on overlapped ends of the strip to produce cuts 4 and 5, Fig. 13, in the strips and bend a portion 6 out of the plane of the strips, strip 1 is then moved longitudinally with respect to strip 2 so that the cut portions interengage each other, Fig. 14, and the lap joint so formed is compressed by rollers 18 to form a secure joint. The strip 1 is first braked and held by rollers 18 and its end depressed by fingers 33 whilst rollers 17 feed the leading end of strip 2 up to fingers 33 before it too is braked. After punching, the punches 27 and a hold up 30 hold the strip ends together while the rollers 18 move strip 1, strip 2 still being braked by rollers 17. The strips are guided through the machine by guide rollers (16), (19) and (34), Fig. 1 (not shown), and guides 30, 31, Fig. 4. The punches are mounted on a table 23 which is mounted on an hydraulically actuated beam 21. Guides 25, fixed to table 23 and passing through holes in a fixed die holder 24, ensure correct location of the punches and dies.

Patent GB-2057802-A (GB)
Title: Differential phase shifters
IPC: H03H11/20
Filed: 1979-08-15
Abstract: A differential phase shifter which provides a phase shift of a signal in dependence on the amplitude and frequency of that signal includes a tuned circuit 4, 5; means for varying the Q of the circuit in dependence on the magnitude of the received signal; and a path in shunt with the tuned circuit and acting to ensure that the phase shifter has an attenuation which is independent of frequency. As shown the received signal is applied to input terminals 1, 2 and the phase corrected output is delivered at 20. The means for varying Q, and thus the degree of phase shift, comprises diodes 11, 12 and means for varying their bias. The shunt path includes resistors 8, 9. No phase shift is imparted to a signal having a frequency equal to the resonant frequency of the tuned circuit. The invention is particularly applicable to a television signal which includes two separate frequency components. By arranging that the resonant frequency is equal to one of the frequency components the phases of the two frequency components can be adjusted relative to each other, in dependence on the amplitude of the signal applied to the phase shifter. The phase of a colour sub-carrier can thus be adjusted in relation to a main vision carrier. <IMAGE>
